What is BDC?

Batch Data Communication or BDC is a batch interfacing technique that SAP developed. It is mainly used for uploading data into the SAP R/3 system. BDC works by simulating the user input from transactional screen via an ABAP program.

The data input data file will come in the form of a flat file which the user save as file type txt file or prn file from the Microsoft Excel program. An Abaper will create a program to read the text file and upload into the SAP system.

Normally, the tcode SHDB will be used to record the transaction code the user used. After, the simulation, the Abaper can generate a sample program and modify from there. It makes the programming easier and faster.

U can find more details from this link.

Batch Data Communication (BDC) is the oldest one. BDC is not bi-directional; it is an integration tool in its typical form. It can only be used for uploading data into RJ3. BDC works through an ABAP program and works on the principle of simulating user input for transactional screen.

The purpose of the Batch Data Communication is to transfer data. The BDC can transfer data from one SAP System to another SAP System or can transfer data from non-SAP System to SAP System too. To transfer data BDC uses normal transaction codes. Two methods are provided to BDC to do this work.

SAP has provided two different types of methods for BDC to do its work. Among these, the first one is called the classical method or session method. Through this method the data can be read by the BDC program from a sequential dataset file. This sequential dataset file is stored in batch-input session. In order to .run the transaction in this session, what one needs is to execute the session. For this, follow these few steps: you can start and subsequently monitor the session firstly from – System à Services à Batch Input or have the session run in the background. In this method to generate the required session, you have to use the function module BDC _ NSERT and BDC _CLOSE.

In the second method the BDC has to use the ABAP statement CALL TRANSACTION USING statement to run a transaction. In the second method, unlike in the first type, you do not need BDC to create a session.

During the process of data transfer, data is transferred into the SAP R/3 System. This transfer is from an external system to SAP R/3 system. Whenever you transfer data from an external system into an R/3 System, you can use data transfer because it is installed and regularly transfers data from an external system into an R/3 System.

Direct Input: In this method the SAP function modules execute the consistency checks. However, there are other means of checking with the help of screens. The Direct Input Method has considerable performance advantages.

Call Transaction: In this method you can check the data consistency with the help of screen logic.

Batch Input Session: In this method data consistency is checked with the help of screen logic.
